Abstract in another language

In the present work material-specific engineering parameters are defined, which allow to estimate and optimize the efficiency of high-temperature microwave heating processes for a wide range of temperatures. For this aim analytic calculations based on Mie theory were performed, and simplified characteristic numbers were compiled. For the design of real processes a flexible coupling of microwave and thermal simulation of the heating behaviour of ceramic materials, which is considering changes in sample size during sintering, is suggested - aiming at sufficient energy efficiency and process stability. From the sum of results a guideline for the process engineer is developed, which shall support evaluating the material-related feasibility of microwave heating as well as supporting the process design of a microwave heating process.
